Overview
CVE-2025-33192 is a medium severity vulnerability affecting NVIDIA DGX Spark GB10 systems. This vulnerability resides in the SROOT firmware and allows an attacker to potentially perform an arbitrary memory read, which could lead to a denial-of-service (DoS) condition.
Technical Details
The vulnerability stems from a flaw within the SROOT firmware of the NVIDIA DGX Spark GB10. Successful exploitation allows an attacker to read arbitrary memory locations. The precise attack vector and the specific firmware components involved are detailed in NVIDIA’s security advisory (linked in the References section).
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) score for CVE-2025-33192 is 5.7, indicating a MEDIUM severity. This score considers factors like the attack complexity, attack vector, and the potential impact on confidentiality, integrity, and availability. A score of 5.7 typically suggests that the vulnerability is exploitable with some effort and can have a significant impact on system availability.
Possible Impact
The primary impact of successfully exploiting this vulnerability is a denial of service. While the vulnerability involves memory reads, the consequence is that the system may become unstable or unresponsive, rendering it unusable. The ability to perform arbitrary memory reads could potentially be chained with other vulnerabilities for more significant impact, although CVE-2025-33192 itself is rated as medium severity.
Mitigation and Patch Steps
The recommended mitigation is to update the SROOT firmware on your NVIDIA DGX Spark GB10 systems to the latest version provided by NVIDIA. Check the NVIDIA security advisory (linked below) for specific instructions on how to download and install the updated firmware. It is crucial to follow NVIDIA’s recommended patching procedure to ensure the vulnerability is properly addressed. Regular firmware updates are vital to maintaining the security and stability of your NVIDIA DGX systems. Monitor NVIDIA’s security bulletins for any future updates or recommendations related to this and other vulnerabilities.
